Spectacular Mirima National Park is only two kilometres north of Kununurra and covers 2,068 hectares. It has rock formations like a miniature version of the Bungle Bungle Range in the Purnululu National Park. Mirima is the name given to the area by the Miriuwung people, who still live in the region and consider this area to be especially significant to their culture. It is also aptly known as the Hidden Valley.

A stones throw from Kununurra, and yet a world away, is a valley with rugged cliffs forming amphitheatres, gullies and ridges. It is in this secluded spot where the Aboriginal people have lived for thousands of years.

In daylight the steep and broken walls of rock come alive as they reflect the tones of changing light. In the late afternoon, shadows form imaginary faces which stare in silence as birds of prey wheel in the sky over this intricate maze.

This is the Hidden Valley of Mirima National Park. Within the park you will find the rugged scenery of an eroded sandstone range, varied plant and animal life adapted to the seasons of wet and dry, as well as fascinating evidence of past Aboriginal use. The ancestors of the Miriuwung people left a heritage of rock painting, engravings and artefacts. Please do not touch any paintings as it may cause them to deteriorate!

Most of the 750 millimetre annual rain in the area falls during the wet season from January to March. Daytime temperatures are hot most of the year, the coolest months being June, July and August.

Gradual erosion of the Quartz Sandstone by the waters of Lily Creek and its tributaries has created a large number of cul-de-sacs, amphitheatres and twisting valleys. The rock is some 350 million years old and its sedimentary
nature can be seen in the layers or strata in which it has been laid down.

Several species of Eucalyptus dominate the area and these include the aptly named Woolybutt close to the cliff bases, and the long fruited bloodwood which grows in the moister areas of the main valleys within the park.

Frogs, Tortoises, Geckos, Goannas, Snakes and other reptiles can sometimes be seen, especially near the waters of Lily Creek. The observant may encounter the agile Wallaby or the short-eared rock wallaby, fruit and insectivorous bats, dingoes or an echidna. Birds of many types abound in the area including the Black Kite, the seed-eating Finches, Quails, Pigeons, including the White-Quilled Rock Pigeon, and many more. A comprehensive bird list is available and further information on the fauna can be obtained from the ranger and CALM.

The flora of the area is mainly low spinifex and scrub which is pretty Maleovent, Boab trees and some Eucalyptus.

No camping permitted in the national park. Camping available at caravan parks nearby.

Views to Kununurra and over surrounding areas can be seen from a number of scenic vantage points. Try one of these signed walks, or ask the ranger about other points of interest.

Walk 1 - Lily pool:
A 100 metre return easy walk featuring examples of stone axe grinding grooves above the lily pool. Here the use of water, sand and repetitive rubbing established a cutting edge on stone implements. Please stay on the defined trail. The area is fragile.

Walk 2 - Wuttuwuttubin Track (meaning short and narrow in the Miriuwung dialect:
A 500 metre return walk within a steep-sided gorge offering a view through to Kununurra airport.

Walk 3 - Didbagirring track (lookout):
A difficult walk of one kilometre up steep slopes with some loose rock, but the adverturous walker is rewarded with views of the area and the bungle-bungle like rock formations of the hidden valley.

Caution:
Much of the rock in hidden valley is brittle and crumbly. Do not stand on or walk close to cliff edges. Stay on marked tracks or, if venturing further, ensure that someone knows your proposed route and time of return.

No open fires are permitted and no firearms or pets.
